Iron(III) azide, also called ferric azide, is a chemical compound with the formula Fe(N3)3. It is an extremely explosive, impact-sensitive,

anti-Markovnikov addition of azide group.[2]

Preparation

This compound is prepared by the reaction of sodium azide and iron(III) sulfate in methanol:[2]

6 NaN3 + Fe2(SO4)3 → 2 Fe(N3)3 + 3 Na2SO4

Iron(III) azide can also be formed by pulse

oxidizes
the iron(II) to iron(III); the iron(III) then promptly combines with azide ions.
